Therapeutic Potential of Cornus Genus: Navigating Phytochemistry, Pharmacology, Clinical Studies, and Advanced Delivery Approaches

The genus Cornus (Cornaceae) plants are widely distributed in Europe, southwest Asia, North America, and the mountains of Central America, South America, and East Africa. Cornus plants exhibit antimicrobial, antioxidative, antiproliferative, cytotoxic, antidiabetic, anti-inflammatory, neuroprotective and immunomodulatory activities. These plants are exploited to possess various phytoconstituents such as triterpenoids, iridoids, anthocyanins, tannins and flavonoids. Pharmacological research and clinical investigations on various Cornus species have advanced significantly in recent years. Over the past few decades, a significant amount of focus has also been made into developing new delivery systems for Cornus mas and Cornus officinalis. This review focuses on the morphological traits, ethnopharmacology, phytochemistry, pharmacological activities and clinical studies on extracts and active constituents from plants of Cornus genus. The review also highlights recent novel delivery systems for Cornus mas and Cornus officinalis extracts to promote sustained and targeted delivery in diverse disorders. The overwhelming body of research supports the idea that plants from the genus Cornus have therapeutic potential and can be investigated in the future for treatingseveral ailments.
